TL;DR Jack is recognized as input and I want to use it for output. Also how can I output sound to both speakers and headphones at the same time? Hello! Yesterday I have installed the elementary os for the first time, right now I'm at my 2nd installation. I have a problem with my jacks, only 2 out of three seem to work, one for audio and one for the microphone. I tried searching google on how to use speakers and headphones at the same time and I end up breaking my system and making sound card undetectable, right now I'm on a fresh install. I can only use the headphones if I unplug the speakers from the working jack and plug the headphones, and vice-versa. I'm on a PC, not a laptop. Also at this moment I have noticed that the third jack is recognized as an input device. 2/3 jacks work. 1 - (input) - mic - working 2 - (output) - speakers - working 3 - (input) - headphones - not working
